Epic Games Launcher Error SU-PQR1603

Hello Everyone,

The epic games launcher got an update today and when ever I try to update, I get this Error SU-PQR1603.
I did some googling and I found that you just need to add -SkipBuildPatchPrereq lunch argument.
But lutris already has this in by default.


Any ideas?

I’m having the same problem. Looks like Epic pushed an update that broke things

Anyone have a workaround yet? I am facing the same issue. Also does anyone have a wine bug report filled yet?

Updating with a fix that worked for me:

WINEPREFIX=~/Games/epic-games-store WINE=~/.local/share/lutris/runners/wine/ge-protonified-4.9-x86_64/bin/wine ~/.local/share/lutris/runtime/winetricks/winetricks dotnet48
Fixed the issue for me. After getting dotnet 4.8 installed, Epic games launcher was able to complete the update successfully.


Were re-installing my system and installed Lutris and EGL again. Everything works fine.

This worked for me, mind you I did do a complete re-install too.
